The connections for blowing oil steam (see Fig. 7) into the blow-off main each comprise a'valve 1 9, connected to main 10, pipe 20, pipe-standard 21, and a pipe 22, one end of whichis adapted .to be connected to a valve 23, usually provided in the dome of the boiler. Pipes 21 and 22 are providedwith flexible joints 24 for convenience-in connecting'the dome of the boiler to the blow-off and feedwater mains. When this connection to the dome has been made, the blow-oil steam can pass through pipes 22 21 and valve 19 into the blow-oli' main 10. The connection, comprisingpipes21 and 22,.serves also as a filling connection.

A pipe 20 is connected to pipe-standard 21 and to a valve 23, which is connected to,

feed-waterinain 1 1. (See Fig. 7.) This connection makes it possible to introduce f dwater into the boller through the dome cdnnection. nected by a 'pipe standard or leg 24 to branches '25, which have terminals adapted to be connected by flexible pipes; such as 17, to the blow-off cocks at the sides of the locomotive. A valve 27 controls supply of feed- Water to branches 25, and a valve 28, adjacent one terminal of one of the branch pipes 25, controls passage through said terminal.

Valves 32 and 28 control passage of feedwater to the other terminal of pipe 25.- Obviously. by means of valves 28, 32, and128' feed-water can be supplied through either or both of the branch pipes to the boilers adjacent the leg 24.

The wash-out main 12 is connected to sup- .ply washing-water to branches 25 by a pipestandard 29, which is' connected to said branch and is provided with a valve 31 for controlling the passage of washing-water to said branches. Valve 32 is, arranged between the couplings 25 and ipes 24 and 29 to cut ofl" commu'nication t erebetween, so that the terminal at one side can be used for refilling, while the terminal at the otherside can be used for washin By of valves 27, 28, 32, an 28 either or both of the terminals of branch 25 can be used for supplying water to a wash-out connection.

low-ofi' main 10 conducts the contents of the locomotive-boiler (steam and water) to a pipe 10, connected to a separator 37, Fig; 4,

whereby the blow-ofl steam is separated from the blow-'o'fl water.' The. steam passes by a pipe- 38 .t0 a feed-water reservoir and heater A, and the blow-off water and impurities therein pass through a pipe 39 toa reservoir B for the washing-water. It .will thus be seen that the 'blow-ofl steam and blow-offv water can be sim ultaneously discharged from the locomotive-boiler t'hrr'iugh a common The feed-Water main is also conexcess blow-off water to the sewer. count of such construction the coldest por- -cold water which is mixe manipulation pipe and then separated, so that the steam can be used to heat-the feed-water and the impure blow-ofi' water sent to the reservoir for the washing-water. I I

Reservoir B for containing the washingwater is provided near one end with a strainer or filter C, Fig. 2, at one side of whiclris'arranged a chamber b for the purified blow-off water, and at the other side of which is arranged a receiving-chamber b for the blow-oil water as it comes from the boiler and to which .pipe 39 is connected. 'The blow-ofi' water passes from the receivingchamber I) through filter G into the storagechamber 5. The strainer purifiesthe blowoff water sufliciently so it can be used to advantage in washing out the boiler. This strainer or filter is preferably mounted in a removable frame a, which can be withdrawn and replaced through an opening in the top of the reservoir. The heavierportions or foul contents of the boiler settle in chamber 1) and may be withdrawn, when desired, through a discharge-pipe 40, controlled by a valve 41 'and leading. to a'sludge-tank 42. An overflow-pipe 43 terminates near the lower portion of chamber 6 and condugts the tion of the water in the reception-chamber passes to the sewer.

. The washing-water should be used at a temperature ran ing from 100 to 130 Fahrenheit, and t e blow-off water as it entersreservoir B is usuall of a much higher temperature. Resultant y it frequently ocours that the filtered water in reservoir B is too hot for washing. A pipe 45, usually connected to the water-sup ly main,'supplies with'the purified blow-off water, to temper the water supplied to washing-main 12. A pipe 80 is connected to the bottom of reservoir B and conducts the purified blow-ofl' water to a reservoir 81. A valve 82 is included in said pipe and is automatically operated by a float 83, so that reservoir 81 will always contain a supply of water at suitable temperature for washing. Cold-water pipe 45 is connected to a tank 84,

and'a valve 85, which is controlled by a float 86 in said tank, automatically regulates ,the supply of cold water to said tank. a A thermostatically-controlled butterfly-valve 46 is included in a pipe 87, which connects pipe and tank 84 and Cohtrolsthe su ly of cold water to reservoir 81. Purified Blew-off water in reservoir B is not under pressure, and

the purpose of tank 84 is to ,reduce' the pressure under which the cold water is usually supplied inmain 45, so that the pressure of the cold water and the hot water passing to reservoir 81 will be substantially equalized. This feature is important, because unless the pressures are equalized the water under greater pressure will preponderate and eil'ect a sudden change of temperature of the wash-' jig-water in the mixing-tank. By thus substantially equalizing-the pressure of the wa-- ter in pipes 80 and 87the temperature of the water in reservoir 81 can be regulated toa nicety. Valve 46'is normally spring-pressed into closed position and is opened by fluid under'pressure supplied thro h a pipe 88 restore the valve to closed position and hold 'into a chamber 89, formed in t e v ve-cas- Fluid in' chamber 89 acts upon a diaphragm 9.0, which operates a lever'91, connected by'a rod 92 to an arm 93, 'secured tothe stem of the butterfly-valve Springs 94 said valve normally closed.

A thermostaticregulator N, Fig. 8, controls the su ply of fluid under pressure to pipe 88 and utterflyvalve 46. A pipe 100 for fluid under pressure- 9., water or airis connected to a suitable source of supply and conducts said fluid to the regulator. A filter 1- and a pressure-reducing valve 102 of usual construction areincluded in said pipe .vided at its inner end wit 100, and the reassure-reducing valve 102, of usual const ction,.is adapted to supply fluid under desired pressure to a fluidort 99 in the casing of the thermostatic re ator. The

regulator comprises a tube 95, located in reservoir 81 and containing an expansible fluid phra the exhaust valve 104 and resses the seat of said valve away from sai valve when said stem is moved inwardly as a result of the contraction of the medium 96 in pipe 95. An adjusting-nut 110 for regulating the operation of valve 103 is provided, and a reliefspring 111 is interposed between the restraining-spring 98 and the valve-stem.

When the parts areinnormal position (shown in Figs. 8 and 9) andthewater supplied to reservoir 81 by ipe 80 is too hot for washing out a boiler, me 'um 96 will expand, and thereupon stem 106 will be operated to open admission-valve 103 and to close exhaust-valve "104. Thereupon fluid under-pressure from w and temper the water.

pipe 100 will pass through port 99 in the regulator to pipe 88 to operate the butterflyva ve 46 against the force of .its retainin springs 94 to open, said valve, whereupon cold water from tank 84 will flow to reservoir 81 When the temperature has been lowered to the desired point,

s 107 and 108. A spring 109 is inter pose betweenthe outer end of stem 106 and.

' the medium 96 will contract, and thereupon admission-valve 103 will be closed andex haust-valve 104 will be opened, so the fluid in pipe 88 can esca 0, via a portl 13, to a chamber 112 and out et 115.

A steam-pump D serves to force-the water in reservoir81 to the wash -out'j main. .The

inlet of said'pum is connectedtoreservqil 81 by a pipe d, an the dischargeof the pump,

1s connected by a pi 'e d to wash-out mam 12. AIva'lve 49 is a so provided for cutting off the supplyof water from'reservoir'B to the pump w en desired." D is of usual construction arid 'operated by steam conducted thereto by a pipe 50,:fand itsoperation is controlled by a suitable governor d e. g. ,such as is commonlyknown-as a Fisher governor-Whichis operated by the ressure' of the water in pipe (1 to automatica start andstop the pump and maiz itain esired pipe d is connected to oneend of'main 12 and to the reservoir. It is important to keep the washing-water in the main at the ro er temperature. If it should cool, there IS li elihood of injury to the boiler at the outset of a washing-out operation, when the cool water comes in contact with the hot walls of theboiler or crown sheet. By maintaining at least a slow circulation of washing-water when the washing-out s stem is notbeing .used all likelihood of suc injury is avoided.

. Marifestly this apparatus utilizes the blow-off water'for washing out the locomotive-boiler and, furthermore, saves to the fullest extent the heat units in the blow-ofi' water and in the sediment blown oil-from the boiler and renders operation'of the plant extremely economical, because both the water and the heat units of the blow-off Water are utilized. Furthermore, the water for Washing is supplied to the roundhouse-main at the proper temperature for washing without the'necessity of mixing hot and cold water at the discharge connection. The temperature of the washirg-water is automatically and thermostatically regulated, and thus always at the proper temperature to avoid 'injuryto the boiler. washing out need not mix cold and warm wa- Bit? pressure in main',12. A small circulating.

The workman employed for ter to obtain water of the proper temperature for washing out the locomotive-boiler. Furthermore, the workman at the roundhouse cannot change the temperature of the water used for washing, 'ch always arrives at the wash-outbonnection at the proper temperature. The disposition of some workmen is to use washing-water at-too low a temperature, since that is easier to wash out with; but

with the improved apparatus the-workman is obliged to use at all times washing-water at the proper temperature, and therefore'frac- I ture of the boiler or crown sheet cannot occur as a result of the use of water which is toocold for washing. 1

' 37 for checking the-passage of steam through the separator with the blowofi water, The steam passes from separator 37, through pipe 38 to feed-water reservoir A. This heater is provided with a steamTchambe'r a at each end and circulating-pipes a in desired number, wherethrough the steam will pass from the chamber at one end of the reservoir to the chamber at the other end. Around the pipes and between heads a is formed a chamber for the feed-water used 'for recharging a boiler. A small pipe (1 is connected to the chamber a at one end of heater A to permit the steam to slowly escape. A trap 11. is provided for the water of condensation in the heater. Fresh water is supplied to reservoir A by a pipe 54, which is connected to the cold-water-sup ly pipe 45. A float 55, Fig.

' 6, automatical y controls a valve 56, which .fectedin about four to eight minutes.

used: to force the'water controls the supply of fresh water to the feedwater reservoir, so that a body of fresh water will at all times be within the beaten. The blow-off steam passing through. heater A materially raises the temperature of the feedwater. A'valve 57 is provided in pipe 38, through which the" blow-off steam enters heater A, so the blow-off steam can be discharged in reservoir B, if desired. The blow,- ing-off operation with the improved apparatus consumes a very short period because the steam and water can be simultaneously discharged fromthe locomotive-boiler, and by using a large blowoif main throughwhich both the steam and waterare blown off the blowing-off operation can ordinarily be ef- Fur thermore, by cutting oif the blow-ofi steam atthe dome connection the steam can be from the boiler into reservoir B. Y

Thefeed-water for recharging the boiler is forced into the boiler at a pressure of about one hundred pounds'and at a temperature of about 300- Fahrenheit. The superheated water discharged into the boiler results in rapiddifiusion of sufficient steam, so the 1000- motive will when charged be immediately put into condition for service.

A superheater E, Fig. 5, is provided for raising the temperature of the feed-water before it is supplied to the locomotive-boiler. The superheater is preferably a fuel-heater, comprising a firepot e and a boiler e, which contains feed-water from heater A. In this superheater the temperature of the water from he'ater A is raised to supply the deficiency in temperature necessary in charging in such manner that the locomotive will be quickly restored to serviceable condition. A fuel-heater as distinguished from other heaters, such as steam, is of importance, because thermore, because it ispossible thereby to as quickly as desired. By banking the fire I I when the apparatus is not in use a material saving of fuel will be eflected. For these reasons a fuel heater or boiler o erated directly by the heat generated by fue is of advantage in the practice of the invention: Manifestly the feed-water is raised to the desired temperature in an economical manner, because the blow-off steam is utilized to raise the temperatureof the feed-water (sometimes as Fisher governor 64, which controlsthe oppressure in the feed-water siipply line will always be maintained. Steam for the operation of pump F is supplied by a pipe 65. A small circulating-pipe 66 is connected to the feed-water main 11 and to'pipe to maintain circulation in the feed-water line, and thereby the feed-water throughout the supply-line will always be kept at the desired temperature, so as to avoid a fracture likely to result on injection of cool water. Pipe 45 has direct connection, as at 45, with pipe 38,

Under the pressure within the boiler the water and steam will be quickly blown off and into the blow-off main 10. If desired, cock 23 can be left closed until the water"v has been -blown off and then reservoir A to raise the temperature. of. the

In this manner sufiicient hot water for washing out the boiler is. provided, since the amount of blow-off water in a locomore .sufiicient When the blowing-off operation is com- I pleted, cocks 23 and 16 are closed. A hose or washing put the boiler is then connected to pipe-terminal 25. Valves 28 or 28' and 31 -are then opened, when watergsup lied from tank 81 by force-pump D w ll pass om main 12, throu h pipe 29and thebranch 25, to the hose use for washing out'the'boilerl If desired, such a connection can be made at each side of the boiler, so two workiii'en can simultaneously wash out a boiler, which is desirable when a locomotive 'is to be. kept out of service as little as possible. 1 i

Manifestlythe washing-out connection ca be performed by the'workman without a y regulation on his part because of the app ratus employed for automatically regulating the temperature of the'wash-out water and by which it is always maintained at the 1 desired temperature in the mixingtank 81. When the boiler has been washed out, a hose connection" 17 is connected to, each of the branch pipes 25 on opposite sides-of the locomotive, and the necessary valves are opened (27 and 28 on one side and 32 and 28' on the other) and conduct water from main 1 1, thro gh ipes-24,hose connections 17, and the 11105705 cocks 18 to the boiler.

In railroad practice treated water is sometimes used' 'i. 0., water treated, withincrustation preventives or. compounds-rand ,then it'is not necessary to wash out th at least notfrequently. that driigcactice, however, it is frequently desired to barge the im ure water containing, lated chmpounds in suspension and to replace the same by freshwater. With' the improved apparatus described it s ssible to simultaneo sl blow off and rep water in the 0' er by pure water without putt' out, distributing, or hanhnfihe fire in the e-box of the locomotive. at can be done in the following manner, viz:

For this pub pose it is not necessary to bank or put outthe fire. entire recharging operation, thus avoiding the material changc'of temperature and resultant expansion and contraction which strain the boiler. By this imprOved'apparatus impure water can be frequently replaced in a very short period, and by occasional replacement the life of a locomotive is materially lengthened without washingout the locomotive-boiler.

By the improved apparatus many of the dif-' ficulties heretofore encountered in the use of equipment for washing out and refilling locomotive-boilers are overcome, because the plant can be operated at a low cost of 1naintenanee, and it becomes possible and practical to frequently wash out or refill boilers without lengthy interruption of the service.

Manifestly, the invention is not to be un-- derstood as restricted to the particular construction setforth, but may be modified within'wide limits without departing from the spirit and scope of the invention.
